Variable when calling text file content

Folks:

I’m down with calling up content from external text files. No problems there. What I’d like to know is this:

If the text file has a number of parts being called up like this:

&text1=this is the first piece of text.&
&text2=this is the second piece of text.&
&text3=this is the third piece of text.&

Can I have a single text box call each of these when necessary? I know different pieces of content can be called from separate text files (like here http://www.kirupa.com/developer/mx/multiple_dynamictext.htm) but I only want to use one text files with all the info.

So:

Can the “text1” part of the following piece of code (which retrieves the appropriate piece of text from the text file) be a variable?

bodytext.htmlText = this.text1;

Any help would be great.
